Unfortunately I think you're out of luck on the departure route.
VS as far as IK has a partnership with
Delta and Delta only. With no affiliation to Skyteam from what I can tell. On the way back however, you're all set for the DL arrivals lounge

-as well as a ton of skyclubs as you know already.
Was a pleasant twitter convo with you by the way
PS. I'm betting on that you know about Priority Pass. If you have it, there's 3 lounges right in T3 that accept it (being the ServisAir, Air Canada and the No1 lounge). Just thought I'd put that out there
True, and on the OP's route, the lounge benefit is only offered to DL DMs and PMs (noot GMs, so not all of Sky Priority or SkyTeam ElitePlus) in coach.
